PureTech launches Celea with $180 million financing to advance Phase III IPF program

2 July 2026

UK biotherapeutics company PureTech Health (LSE: PRTC) says its founded entity Celea Therapeutics has completed a $180 million financing to advance deupirfenidone (LYT-100), an investigational treatment for idiopathic pulmonary fibrosis (IPF), into Phase III testing.

The financing was backed by RA Capital Management, Leaps by Bayer and PureTech, alongside an unnamed large US healthcare-focused fund and a sovereign wealth fund. Proceeds will support the planned early third-quarter 2026 start of SURPASS-IPF, a pivotal head-to-head Phase III trial comparing deupirfenidone with Roche’s (SIX: ROG) Esbriet (pirfenidone).
